Hi Balázs,

Thanks for the answer. But, My question is: It is possible to include a external python script.

e.g:

$ cat foobar.conf:

python {

@include "caipirinha.py"

}

template-function foobar "$(python foobar)"

$ cat caipirinha.py

from foobar import foobar_template_function

# my python class/code is separated

...........

got it? maybe using the "confgen" module?

Hi,

The example Python code should be unindented, or you see a different error?

Also, you can always import code in the python block.

With destinations you can specify a path to a python file, so the python block is not needed. But with template functions I've figured the $(python) call would be too crowded if we were passing explicit filename parameters.

But you can encapsulate the python code as well as a wrapper to the python code into a separate file.

Foobar.conf:

python {

from foobar import foobar_template_function

}

template-function foobar "$(python foobar)"

----------

Then you can use:

@include "Foobar.conf"

...
template("$(foobar)");
...

Unfortunately then template function declarations cant take parameters yet from the callsite, which may be a serious limitation in your use-case. But with a conceot above you can completely hide implementation details your actual config.

Well, based on this[1] document. We should use the python {} statement. But, I would like to keep my python script externally in a separated file and do something like.

python filter_001 {
/my/script/python001.py
}

log {
....
filter(filter_001);
....
};

p.s: Btw, this sample https://www.balabit.com/documents/syslog-ng-ose-3.7-guides/en/syslog-ng-ose-guide-admin/html-single/index.html#example-python-template-functions don't work in the syslog-ng 3.9.1
